IMPROVEMENT IN WATER-WHEELS.

TO ALL WHOM IT MAY CONGERN:

Be it known that I, W. I-I. ELMER, of Fair Water, in the county of Fonddu Lac, and State of Wisconsin, have invented a new and improvedl/Vater-W'heel; and I do hereby declare thatthe following is a full,clear, and exact description thereof, which will enable those skilled inthe art to make and'use the same', reference being` had to theaccompanying drawings, forming part of this specification, in which-Figure I is a vertical central section of my invention taken in the line:c x, iig. 2.

Figure 2, a horizontal section of the same, taken in the line y y, tig.l.

Similar letters oi' reference indicate corresponding parts.

This invention relates to a new and improved horizontal water-wheel, andit consists in anovel andimproved manner of applying the water to wheelwhereby several important advantages are obtained, as hereinafter fullyshown andfdescrbed. l

A represents the wheel, which is of annular form, and has its shaft, B,stepped in a frame, O,.the wheel resting on a yoke, D, which is rmlykeyed or otherwise secured on the shaft, as shown in g. 1. E representsa cylinder case, which is supported by standards, a, from the frame C.This case, it will be seen, is Xed or stationary, the shaft B extendingcentrally upward through the same. At the lower part of the case E thereare four inclined spiral chutes, F, which conduct the water to thebuckets G of the wheel1 The wheel A, it will be seen, encompasses thechutes F, the case E being cverthe centre of the space within the wheel,and the water consequently enters the wheel at its inner side, and isdischarged at its outer side. The buckets are composed ot' a radialportion, b, and an outer segmental portion, c, issues d being betweenthe portions c, as shown in iig. Q. The water `acts by impact againstthe portions L of the buckets, while the segmental portions c retain thewater or prevent its too ready escape. 'lhe chutes F direct the water tothe buckets, so that the former will impinge against the latter at rightangles. The water is admitted into the ycase E through an opening, e,and it is designed to have the supply greater than the discharge, sothat a full pressure and head will always be obtained. By thisarrangement .there will be but little loss of power by friction of thewater in passing to and through the wheel. The water has a less distanceto travel in passing through `the wheel than when an external curb isused, and in case of repairs'the wheel is easily rendered accessible byremoving the case E.

Having thus described my invention, what I claim as new, and desiretoisecureby Letters Patent, is-

A horizontal water-wheel provided with buckets Gr, composed of radialand segmental portions, b c, as shown, in combination with a centralcase, E, and chutes F, all arranged to operate substantially in themanner: as set forth.
